Shrub rose plant named Ausdir

ABSTRACT

A shrub rose having red-purple, old-fashioned-shaped flowers; spreading growth; and repeat flowering.

The present invention relates to a new and distinct variety of roseplant of the shrub class which was originated by me by crossing thevariety "Prospero" with an unnamed seedling.

The primary objective of this breeding was to produce a new shrub rosevariety that is repeat flowering and has red, old-fashioned-typeflowers. The objective was substantially achieved, along with otherdesirable improvements, as evidenced by the following unique combinationof characteristics that are outstanding in the new variety and thatdistinguish it from its parents, as well as from all other varieties ofwhich I am aware:

1. Deep red to red-purple flowers;

2. Spreading growth;

3. Old-fashioned shape of flower; and

4. Repeat-flowering.

Asexual reproduction of this new variety by budding, as performed atAlbrighton, Wolverhampton, England, shows that the foregoingcharacteristics and distinctions come true to form and are establishedand transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
